RELEASE_NOTES
View file @ 7010d391
......@@ -5,12 +5,14 @@ This file contains the release notes for the ELPA 2015.02.001 version
What is new?
-------------
a)
a) ABI change
---------------------
Most importantly, the ABI of the ELPA libray changed!
A rebuild/relink of the user code using the ELPA library is mandatory!
b)
b) QR-decomposition
---------------------
The only major change (which results in point a) is in the ELPA-2
part of the library for real matrices:
......@@ -27,15 +29,33 @@ Note, that the environment variable always takes precedence over the setting in
the API call.
Furthernote, that if neither the environment variable or the API keyword are not
set, or set to "no" or ".false.", respectively, then no qr decomposition is used
set, or set to "no" or ".false.", respectively, then no QR-decomposition is used
(i.e. the previous behaviour is maintained).
The QR-decomposition fails, if the chosen matrix size is not a multiple of the
blocksize. The library will give a warning message if this happens and it will
abort.
c)
c) Debug messages
----------------------
By setting the environment variable "ELPA_DEBUG_MESSAGES" to "yes", ELPA will now
print more information if an error occurs.
d) Optimization flags
-----------------------
The configure procedure was adapted to be more consistent. No compiler omptimization
flags are set automatically anymore, this is up to the user at build time
e) OpenMP check
----------------------
The checks for OpenMP in the configure have been improved
Any incompatibles to previous version?
---------------------------------------
